If the character input is a normal input, the inputmode management mode 110 orders thestate detector 112 to detect whether the portable terminal is executing the specific application. Whether the character input is a normal input may be detected by comparing the character input with character data stored in thecharacter database 114. - Thereafter, the input
mode management unit 110 changes the character input mode according to the current state of the portable terminal. - Under the control of the input

FIG. 3 is a flowchart illustrating a process for changing an input mode according to the current state of the portable terminal for continuous input of characters, according to the present invention. - Referring to
FIG. 3 , thecontroller 100 controls the inputmode management unit 110 to detect input of characters using an input tool such as a stylus pen, instep 301. The character input may be detected using input data provided from thetouch sensor 108 to the inputmode management unit 110. The characters include English alphabets, Korean consonants and vowels, numerals, special characters (e.g., <, *, and #), etc. that can be input using the input unit (keypad) 102 of the portable terminal. - If a character input is detected, the process proceeds to step 303; and if not, the process proceeds to step 317. In
step 317, thecontroller 100 performs a present function (e.g., a standby mode). - In
step 303, thecontroller 100 controls the inputmode management unit 110 to detect the input character. Instep 305, thecontroller 100 controls the inputmode management unit 110 to determine whether the detected character is a normal input. For example, under the control of thecontroller 110, the inputmode management unit 110 searches thecharacter database 114 and compares the detected character with the previously-stored character data (e.g., A, B, C, and #) in thecharacter database 114 to determine if the detected character matches one of the previously-stored character data. If so, the detected character is determined as being a normal input. - If the detected character is normal, the process proceeds to step 307; and if not, the process proceeds to step 317. In
step 317, thecontroller 100 performs a present function (e.g., character input detection). - In
step 307, thecontroller 100 stores the character detected through thetouch sensor 108.

step 311, thecontroller 100 controls the inputmode management unit 110 to execute an application corresponding to the first mode. The application corresponding to the first mode is the application set inFIG. 2 . - In
step 319, thecontroller 100 determines if an input mode of the character input application is a direct input mode. - The input mode includes the direct input mode and an indirect input mode. In the direct input mode, characters can be directly input using the
touch sensor 108. In the indirect input mode, characters are input by displaying a keyboard-type key input window on thedisplay unit 104 and receiving desired data from the user through the displayed key input window. - If the input mode of the character input application is the direct input mode, the
controller 100 ends the process; and if the input mode is the indirect input mode, the process proceeds to step 321. - In
step 321, thecontroller 100 controls the inputmode management unit 110 to change the indirect input mode into the direct input mode. Thereafter, process proceeds to step 313. - In
step 313, thecontroller 100 displays the character stored instep 307. Instep 315, thecontroller 100 inputs the read character on the character input window of the application. Thereafter, thecontroller 100 ends the process. -
FIGS. 4A through 4C illustrate display screens of the portable terminal changing an input mode according to the present invention. -
FIG. 4A illustrates a display screen of the portable terminal when the user inputs characters in the first mode. For example,FIG. 4A illustrates astate 401 where characters such as “tomorrow” are input in an idle state of the portable terminal using an input tool such as a stylus pen. -
FIG. 4B illustrates a display screen of the portable terminal when the user inputs characters 403 in the indirect mode of the second mode using akey input window 405 displayed on thedisplay unit 104. -
FIG. 4C illustrates a display screen of the portable terminal when the mode ofFIG. 4A or 4B is changed into the direct input mode 407. At this point, the screen displays the previously-stored characters on a character input window prior to changing into the direct input mode. - Alternate embodiments of the present invention can also comprise computer readable codes on a computer readable medium. The computer readable medium includes any data storage device that can store data that can be read by a computer system. Examples of a computer readable medium include magnetic storage media (such as Read Only Memory (ROM), floppy disks, hard disks, etc.), optical recording media (such as Compact Disc (CD)-ROMs or Digital Versatile Discs (DVDs)), and storage mechanisms such as carrier waves (such as transmission through the Internet). The computer readable medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. Also, functional programs, codes, and code segments for accomplishing the present invention can be construed by programmers of ordinary skill in the art to which the present invention pertains.
- As described above, according to the present invention, the application allowing the use of the stylus pen is executed when the character input is detected. Accordingly, characters can be input using the stylus pen even without execution of an additional application.
- While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
